Saturday, March 6, 2004 Spirit Finds Water Earthly volcano. Credit: georoc.mpch-mainz.gwdg.de NASA announced yesterday that Spirit has discovered signs of water on its side of the planet. While inspecting a rock known as "Humphrey," the rover found evidence that water had been present in the rock during formation or soon afterwards. The rock is volcanic, as expected. Says Ray Arvidson, deputy lead scientist, "The best bet is that water was in the magma." While this small amount of water may seem insignificant, it does mean that when rocks are made on Mars, water is involved. It has long been thought that water has played a part in forming the Martian landscape, using mostly evidence from satellite photos, but now we have evidence that even in a mostly dry area, water plays an important role in creating the layout of the land.
